A closer look at semiconductor packaging considerations in EVs

One of the most critical decisions to be made at the earliest stage of designing a new power converter concerns the packages used for the semiconductors, as pretty much every other aspect of the design hinges on their physical form. This is especially true for the main power converters used in EVs—on-board chargers, DC/DC converters and inverters—as there are tight constraints on the size (and cost, of course) allotted to each. Furthermore, any device that has direct or incidental contact with the AC mains will also need to meet some rather onerous electrical safety requirements which—as a case study below will show—can critically depend on the package used for the semiconductor switches....

Implies that for diy EVs using parts from a Tesla M3 is required for the best possible performance.
 
Tesla's main concerns are cost in quantity, cost of assembly, reliability and high efficiency at low output. Performance comes somewhere after those. If you want to know what the highest performance components are, look inside something like the vw ID.R or the latest Mugen Shinden not a Tesla.
